n-Butene is an important raw material for chemical production and has a wide range of uses. The following is a detailed description of the properties and uses of n-butenes.

1. the nature of n-butene

n-butene is a colorless, flammable, slightly odorous gas, molecular formula C4H8. It has the following properties:

1. Insoluble in water, but soluble in organic solvents.

2. n-Butene has a low boiling point of -6.3 ° C, so it is gaseous at room temperature.

3. n-Butene has high chemical reactivity and is prone to addition, oxidation, polymerization and other reactions.

2. the use of n-butene

n-butene as an important chemical raw material, widely used in the following fields:

1. production of butadiene

n-butene can be generated by catalytic dehydrogenation reaction, butadiene is an important monomer of synthetic rubber, synthetic resin and other polymer materials, widely used in tires, pipes, shoes and other fields.

2. The production of butanol

n-Butene can be hydrated into butanol, butanol is an important solvent and chemical raw materials, can be used for the production of plasticizers, coatings, adhesives and other products.

3. Production of butyl acrylate

n-Butene can react with acrylic acid to produce butyl acrylate, butyl acrylate is a monomer widely used in coatings, adhesives, plastics and other fields.

4. Production of acetaldehyde

n-Butene can be oxidized to acetaldehyde, acetaldehyde is an important organic chemical raw materials, can be used for the production of plastics, synthetic fibers, rubber and other products.

In short, n-butene, as an important raw material for chemical production, has a wide range of uses and can promote the development of the chemical industry.
